Présentation

Description

The SMBJ51CAHE3/52 is a surface-mount TVS diode designed for transient voltage suppression in electronic circuits. It protects sensitive components from voltage spikes (ESD, surges) by clamping excess voltage to a safe level.
Key Features:
- Voltage Rating: 51V (standoff)
- Peak Pulse Power: 600W (8/20µs waveform)
- Low Clamping Voltage: Fast response to transients
- Package: SMB (DO-214AA) for compact PCB mounting
- Bidirectional: Protects against both positive and negative surges
Applications:
- Power supplies, communication ports, automotive systems, and industrial electronics.
Alternate Part Numbers:
- HE3/52 denotes specific manufacturing or packaging variants (e.g., tape/reel options).
This diode is RoHS-compliant and suited for high-reliability environments. For exact specs, refer to the datasheet.
